摘要： A device for desalinating seawater comprises at least three plates (20, 21, 22), at least two evaporation chambers, each of them delimited by two consecutive plates, and entrance means (24) to feed the evaporation chambers with seawater to be desalinated, said entrance means being suitable to feed all the evaporation chambers with seawater from a common source, so that at least one plate is suitable to operate as a condensation surface in one chamber and as an evaporation surface in the next chamber. The device may be arranged in any coastal system that requires a heat flux of low thermal intensity between a hot source (60) and a cold sink (70). The device guarantees said heat flux by means of vapour generation, transportation and condensation, whereby condensed water is collected as a valuable by-product. A method of desalinating seawater comprises the steps of deaerating the seawater to be desalinated and feeding all the evaporation chambers with said deaerated seawater.

摘要： Solid saccharides are produced from an aqueous saccharide solution in a process, where the aqueous saccharide solution is admixed with a carrier liquid in which the saccharides are insoluble and that has a boiling point higher than that of water to obtain an aqueous admixture, and where the aqueous admixture is subjected to an evaporation step. The heat for the evaporation is at least partially supplied by a heated surface area to yield a vapor fraction including water and a residue fraction including solid saccharides and carrier liquid.

摘要： A heat and mass transfer system configured to be a passive system using gravitational force to form a thin liquid film flow on an outer surface of a flow distribution head and downstream conduit member to subject the thin liquid film to heat transfer mediums. The at least partially spherical flow distribution head creates a uniform thin flow of liquid on the outer surface increasing the efficiency of the heat and mass transfer system. The heat and mass transfer system may include a heat transfer medium supply system in fluid communication with internal aspects of the downstream conduit such that a heat transfer medium flows within the downstream conduit while the liquid film flows on the outer surface of the downstream conduit. Rather than conventional sheet flow on inner surfaces of a conduit, the flow distribution head enables sheet flow to be formed on an outside surface of a component.

摘要： The present disclosure evaporation panel systems including a plurality of evaporation panels. The evaporation panels can include a plurality of evaporation shelves that are laterally elongated, vertically stacked, spaced apart from one another, and horizontally oriented; and a plurality of vertical support columns positioned laterally along the plurality of evaporation shelves to provide support and separation to the plurality of evaporation shelves. The evaporation panels can also include a plurality of female-receiving openings which are individually bordered by two evaporation shelves and two support columns; and a plurality of male connectors positioned at lateral ends of both the first evaporation panel and the second evaporation panels. The first evaporation panel and the second evaporation panel can be orthogonally connectable via the male connectors of the first evaporation panel and the female-receiving openings of the second evaporation panel.

摘要： A method of isolating and purifying a product of sugar alcohol or anhydrosugar alcohol hydrogenolysis from a reaction mixture containing sorbitans, 1,2,4-butanetriol (BTO), 1,2,5,6-hexanetetrol (HTO), among other byproducts of a hydrogenolysis reaction of a sugar alcohol and/or a mono- or di-dehydrative product of a sugar alcohol is described. The method involves contacting the mixture having the products of sugar alcohol or anhydrosugar alcohol hydrogenation and other C1-C6 alcohols and polyols with a resin material adapted for chromatography under conditions where the products preferentially associates with the resin relative to other components in the mixture, and eluting products from the resin with a solvent. The method suggests a way for separation of aliphatic polyols generated from the hydrogenolysis of sugar alcohols or anhydrosugar alcohols.

摘要： A process for production of minerals using an evaporation unit comprising an evaporation element for exposing thereof to the atmosphere for evaporation of a liquid solution therefrom. The evaporation element comprises an evaporation surface and a texture for deflecting the solution during movement along the surface, leaving minerals on the surface as a result of evaporation of the solution. The texture allows the minerals to detach from the element under the sole influence of normal forces of nature before the minerals reach a weight capable of damaging the evaporation unit. The process includes wetting the element with the solution, which at least partially evaporates and forms precipitated minerals, at least some of which are left on the surface; and letting the minerals detach from the surface solely under the influence of normal forces of nature before the minerals on the surface reach a weight capable of damaging the unit.
